Answer:
When fuels are incompletely burnt, they release carbon monoxide gas into the atmosphere. This gas is very dangerous as it is poisonous in nature

Answer:
c) 0.10M NaCl
Explanation:
<em>Options are:</em>
<em>a) 0.20M NaCl</em>
<em>b) Very acidic</em>
<em>c) 0.10M NaCl</em>
<em>d) 0.10M HCl + 0.20M NaOH</em>
<em>e) Slightly acidic.</em>

Based on the reaction:
NaOH + HCl → H₂O + NaCl
You can see than 1 mole of NaOH reacts per mole of HCl producing 1 mole of NaCl
Assuming 1L of 0.20M HCl reacts with 1L of NaOH, moles of both compounds are:
1L * 0.20mol/L = 0.20 moles reacts. That means moles of NaCl produced are 0.20moles in 2L. Molarity of NaCl is:
0.20mol / 2L = 0.10M NaCl
That means, right option is:
<h3>c) 0.10M NaCl</h3>

Explanation:
A gene mutation can be defined as a permanent change in the DNA sequence that composes a gene, resulting in the observation that the sequence differs from what is obtainable in most individuals that make up the population. Mutations range from a change in a single DNA building block (change in the sequence of base pairs) to changes in a large segment of a chromosome that includes multiple genes.
Mutation in the color of the wings of the housefly can be passed on to the next generation. If this trait enhances survival of the butterflies, the orange winged butterflies will eventual become extinct and become entirely replaced by the white winged butterflies. This implies that gene pool has been completely modified.
